Hi - I’m looking to replace my Synology DS414Slim NAS units. New Synology units mean I’ll need to sell my first-born’s organs so I’m looking into jerry-rigging my own SMBC solution.
I’ll take the opportunity to run a PLEX server from it plus increase the storage capacity to 80TB (5x 20TB 3.5" SATA III HDD striped with RAID 5 for parity).
While I have 25 years’ experience in IT it’s been mainly in the Windows world with a few (very few) attempts to explore the Linux world so this will pretty much be all new territory for me - but happy to Google, YouTube and read HowTos …
Current thoughts are either:
-
Raspberry Pi 5 with separate cables and drive-tray connected to either RADXA Penta HAT or M.2 NVMe JMB585 5x SATA HAT card - but apparently RPi5 is a tad slower so I’m favouring the following RADXA options (both with 16 or 32GB to remove any potential RAID 5 performance bottle-necks)…
-
RADXA Rock 5B+ with M.2 NVMe JMB585 5x SATA card. I like that I can use an M.2 NVMe for the boot drive as YouTube tests suggest that the OS performance is much higher, which should help with the RAID 5 NAS performance.
-
RADXA Taco with RADXA CM5. I was thinking to use the convenience of the onboard eMMC for OS but apparently M.2 NVME is still faster for that and also more reliable / less prone to errors and also easier to replace? However for my purposes, we could be talking about diminishing returns.
While these options might seem expensive, they’re 3-4 times cheaper than buying an OOB solution from Synology & co.
Does anyone know if:
- RADXA Rock 5B+ or Taco can be used with a 12v DC PSU (circa 150w) to provide power to the 5x 3.5" HDD or do I need to power the drives separately?
- RADXA Taco can handle 5x 3.5" HDD being plugged directly into the existing onboard SATA ports? (i.e. Taco used like a back-plane).
Thanks in advance for any help offered
